For convenience of description, the control board includes a connector portion coupled to the front end of the PCB portion for connecting the PCB portion and an external socket.

First, referring to FIGS. 1 to 3, a box jig for a control board of a vehicle according to the present invention has a main body unit 100, a pair of frame plates 101 and 103, and a plurality of guide units G1 and G2. , G3, G4, and a plurality of cushion units C1, C2, C3.

The main body unit 100 has a rectangular box shape having an open top surface, and has a bottom portion forming a bottom, and a receiving space portion including a long side portion and a short side portion extending from the bottom portion to form a side surface. For convenience of description, the long side portion of the main body unit 100 is referred to as a long side portion, and the short side portion of the main body unit 100 will be referred to as a short side portion.

Preferably, the body unit 100 is made of an antistatic material to suppress the generation of static electricity. Here, various antistatic materials may be used as the antistatic material, and in the present embodiment, polymer materials PC (PolyCarbonate) and PET (PolyEthylene Teraphthalate) may be used. Polymeric materials are environmentally friendly and have the advantage of exhibiting excellent properties in optical uniformity of the surface.

In order to provide an antistatic function, in the past, carbon or metal is coated on the surface, but there has been a problem that the price increases, and a product having an antistatic function has been developed around ABS resin, but a large amount of conductive components are used to synthesize polymers. As a result, prices have risen.

Thus, the present invention proposes a method of injecting ions into the polymer material using the ion beam for the purpose of improving the antistatic function of the main body unit (100). In order to meet this purpose, it is necessary to have a surface electrical resistance of 10 ¹⁰ Ω / sq.
